2. Description of the Related Art As the prior art of the present invention, German published patent DE 37336
See the 92A1 publication.

The cone type partial warper is mainly used for producing a handle warp or a short warp, and the cone type partial warper can also produce a production warp. Each warp band forming the warp band yarn layer is the same as each other and has a repeat shape. They are drawn from the same bobbin on the creel. When the number of repeat threads is large, a large bobbin creel having a large number of bobbins and a large number of bobbin mounting portions corresponding to the number of repeat threads is required. Therefore, a wide production floor is required in the warping factory.

An object of the present invention is to provide a partial warping facility and a partial warping method that provide a precondition for giving a greater degree of freedom of movement when forming a repeat when warping with a cone type partial warping machine. There is.

[0005]

The above problem is that the bobbin creel is a replaceable creel, and two or more bobbin mounting parts are provided correspondingly to each thread drawing part, and the bobbin mounting part is selective. And a cutting device for cutting the yarn from the bobbin side (the yarn side wound on the bobbin side) and the yarn (the yarn cut from the bobbin side). Other bobbin side (other bobbin thread)
The problem is solved by the provision of a coupling device for coupling to.

According to the partial warping equipment having the above structure, each time when one warp band yarn layer is finished by the cone type partial warper, it is possible to change the yarn series forming the next warp band yarn layer. Becomes Therefore, it is possible to generate a larger repeat by using two or more warp bands having a smaller number of yarns than the number of repeat yarns. Therefore, the area occupied by the bobbin creel on the production floor can be kept smaller than before. In addition, a warp band having a number of yarns larger than the number of repeat yarns can be wound. The yarn of the warp band surpassing the repeat is then utilized as the first part of the next repeat which is continued into the second warp band. This enhances the productivity of the cone type warping machine. As a further advantage, the warping process can be fully automated. It is possible to more easily produce a complicated and labor-intensive handle, which is generally used for a template (pattern plate) or a short warp.

[0007] Preferably, at least six bobbin mounting portions are provided corresponding to one thread withdrawing portion which can be replaced. It is usually sufficient to have 6 bobbins, since a fabric usually does not have more than 6 different thread types, especially different colors. further,
In this case, the bobbin mounting part provided is longer,
It is possible to store at least one thread type.

Desirably, the bobbin creel has at least 64 thread withdrawable portions which are replaceable. With this configuration, 64 yarns can be simultaneously processed in the warp band. For example, the number of yarns can be increased by a unit having 16 yarn drawing portions in a modular manner.

It is preferable that the bobbin mounting portion provided corresponding to one yarn drawing-out portion is arranged on the conveyor and is positioned in the vicinity of the yarn drawing-out portion due to displacement (movement or conveyance) of the conveyor. . Such a conveyor can quickly move a desired bobbin to an operating position (near the yarn drawing section).

It is preferable that the conveyor be electrically positionable. In such a case, the bobbin exchange can be automated.

In this way, in the structure in which the conveyors can be electrically positioned, a structure in which each conveyor has a dedicated electric motor is particularly suitable.

[0012] Preferably, the conveyor is constituted by a rotary table type conveyor. A large number of the above rotary tables can be arranged vertically while saving space.

In one embodiment, each conveyor may be comprised of a vertically circulating belt conveyor. Such belt conveyors can be arranged front and back, saving space.

When the yarn cutting / coupling device is configured as a moving device and provided corresponding to a plurality of yarn drawing portions, the design burden is reduced.

In a preferred embodiment, each yarn drawing portion is provided with a corresponding cutting / coupling device. With this configuration, the bobbin can be replaced very quickly.

It is also a preferred configuration that at least one additional second yarn withdrawal section is provided corresponding to the conveyor. In such a configuration, the creel can be selectively used as a replaceable creel or as a creel having a very large number of yarn drawing portions.

Further, it is desirable to provide a process computer for automatically controlling the cutting of the thread, the positioning of the other bobbin mounting section near the attached thread drawing section, and the coupling of the thread. This process computer enables the automatic operation of the partial warping equipment.

It is preferable that the process computer is configured to calculate which bobbin mounting portion should be mounted with which bobbin of which yarn type from the data of the warp card. With such a configuration, the computer can calculate the optimum equipment of the bobbin mounting portion.

Advantageously, the conveyor is provided with an optical indicator for indicating the thread type of the bobbin to be loaded each time and / or the bobbin mounting portion to be equipped with a specific thread type. That is. With this configuration, the bobbin mounting section can be easily mounted.

The solution to the process technology problem is that after finishing one warp thread layer, at least part of the thread is cut from an attached bobbin and one each of the other via a knot or a splicing point. It is made by being connected to the bobbin side (bobbin thread). In this way, the desired pattern can be obtained.

At this time, it is desirable to make the number of yarns the same in all the warp bands except the residual warp band. The number of yarns can be independent of the number of yarns in the repeat, or can be the same number.

An advantageous arrangement is to leave the unnecessary parts of the conveyor separated from the associated bobbin in order to form the residual warp band. Thereby, the cutting device is used to determine the size of the residual warp band.

A plurality of warp strip layers having the same total number of yarns, yarn count, number of yarns / cm and warp width, but different colors are provided.
It is also an advantageous configuration that they are sequentially generated in one warping process. With such a configuration, a plurality of templates (pattern plates) or the like, which are slightly different from each other, can be arranged in the warp warp and generated.

The present invention will be described in detail below based on the preferred embodiments shown in the drawings.

BEST MODE FOR CARRYING OUT THE INVENTION The partial warping equipment shown in the drawing has a cone type partial warping machine 1, the warping drum 2 of which is a cone 3.
Is equipped with. A yarn collecting reed 4 and an automatic take-up device 5 are provided at the front stage, and a large number of yarns 6 are supplied in the form of warp bands 7 via the take-up device 5. Opposite side (right side in Fig. 1)
Has a beam rewinder 8 and is configured so that the warp yarns generated by the cone type partial warper 1 can be rewound on the beam rewinder 8. The above configuration is a general cone type partial warping facility.

In the embodiment according to the invention, the yarn 6 is fed from a bobbin creel 9 designed as a replaceable creel. For this purpose, the conveyor 10 in the form of a rotary table is provided with nine bobbin mounting portions 11 each.
Each bobbin mounting portion 11 carries one bobbin 12. Each bobbin 12 has an operating position 13 (see FIG. 4)
And in this position, the bobbin 12 is adjacent to the thread withdrawing portion 14. The yarn drawing-out portion 14 is provided at a position inside the creel support frame 15. Figure 4
As shown in FIG. 3, the yarn 6 is sent from the yarn withdrawing portion 14 to the yarn collecting reed 4 through a yarn brake 16 equipped with a yarn breakage monitor. Each conveyor 10 can be positioned by a dedicated electric motor 17 (see FIG. 2) equipped with a position indicator so that each selected bobbin is in the operating position 13. Each of the eight such conveyors, one embodiment of the turntable 10, includes a creel support frame 15.
Inside, they are arranged vertically (Table 1 on the right side of FIG. 2)
(See Group 0). As shown in FIG. 4, a stack of eight such rotary tables 10 stacked vertically is provided in a plane as shown in FIG.
4 is formed. The number of the thread withdrawing portions 14 can be further increased by installing other structural units side by side, for example, 16 yarn withdrawing portions can be provided for each structural unit.

As for the automatic cutting / coupling device 18 provided in association with the bobbin creel 9, two identical cutting / coupling devices 18 are arranged side by side, and the respective automatic cutting / coupling devices 18 are arranged in rows. It is possible to pass by 14 sides. The yarn 6 is cut from the bobbin 12 side around which the yarn is wound by the cutting device of the cutting / coupling device 18. The cut end of the yarn 6 cut by the joining device of the cutting and joining device 18 is joined to the other bobbin 12 side (the yarn of the bobbin 12). At that time, the suction nozzle piece 19 is configured to firmly hold the cut thread 6 until the cut thread is again joined to the other bobbin side (thread of the bobbin 12). There is.

The connecting device can be configured as a knotting device, or as a yarn splicing device, a bonding device, or the like. Therefore, one unit of the cutting / coupling / combining device 18 is provided for each of the yarn withdrawing portions 14 arranged horizontally in a row.

If necessary, the process computer 20 controls the operation of the cutting / coupling device 18 and the positioning of the rotary table 10 when the cone type partial warper 1 finishes the warp band yarn layer from the warp band 7 of the yarn 6. It is desirable to be configured to control. Further, as a second role, the process computer 20 calculates which bobbin 12 assigned to various yarn types should be moved to which bobbin mounting section before starting. In order to facilitate mounting of the bobbin 12, each rotary table 10 is provided with an optical display 2.
1, for example with a pilot lamp. Further, the process computer 20 calculates (calculates) which of the many bobbin mounting portions 11 the bobbin 12 of the same thread material should be prepared for. These bobbin mounting parts 1
1 is sequentially displayed by the pilot lamp 21. Another optical indicator 22, for example a display, can display for each bobbin mounting part 11 which color number should be used for the preparation. The illustrated bobbin creel 9 has 64 thread withdrawals 14 in this embodiment. Instead of up to 64 yarns in the warp band, 80, 96, 114, 128 or more single yarns in the warp band are simultaneously warped by adding another unit, for example 16 groups. The more you gain, the larger the bobbin creel can be.

As an alternative embodiment, as shown in FIG. 4, two other yarn drawing portions 23 and 24 are provided at the outer portion of the creel support frame 15, and these yarn drawing portions are provided. It is possible to guide the other yarn 25 to the warp band 7 via the yarn brakes 26 using the bobbin 12 originally prepared for replacement via 23 and 24.
Thus, the number of threads to be processed can be increased to 128 threads / repeat or 192 threads / repeat without expanding the creel.

When operating, it can be processed as follows. The following data is set in the process computer 20, for example. -The total number of threads in the warp, -the number of threads in the warp band 7 (up to 64 or more in another expansion stage),-warp card data, -the front part before the lower thread split and the upper part. Warp length, including the trailing portion after thread splitting, eg assignment of color numbers so that each color can be clearly defined for each of the 64 rotary tables 10, yarn count, eg Nm.

The optimum use of the mounted bobbin can be obtained by the process computer calculating all the data necessary for the production process such as the number of bobbins / colors, the running length, and the weight from the above parameters.

The warping process itself is the same as the known method. Therefore, the twilling string or the sizing pitch will be performed as usual. Here, it should be noted that the binding points, that is, the knots, for example, have a fixed front portion, and all the binding points are in front of the first twill string or the first sizing pitch, so that they are finished. The weaving process does not affect the warp.

In FIG. 5, reference numerals added by 100 to the reference numerals given in the above-mentioned embodiment are attached to corresponding structures. As a substantially different point, the bobbin mounting portion 111 for the bobbin 112 is fixed to a conveyor 110 configured as a belt conveyor, and the conveyor 110 conveys the bobbin 112 to the yarn withdrawing portion 114, and four bobbins are provided. This is the point that the drawer portions 114 are arranged vertically.
When operating, it is the same as that of the embodiment shown in FIGS. Here, as the conveyor 110, a belt conveyor that circulates vertically is used, and each four adjacent yarn drawing portions 114 are formed as operating positions 113. If only the two conveyors 110 shown in FIG. 5 are provided, each yarn withdrawal section 114 will have its own cutting and joining device 118.
